Biological　nervous　system　is　a　complex　multifunctional　learning　system.　Our　brain　can　receive,　judge,　and　remember　different　signals　from　different　sensory　organs,　such　as　hearing,　touch,　taste,　and　so　on.　Constructing　such　an　artificial　perceptual　memory　system　is　critical　for　biomimetic　and　real-time　neuromorphic　computing　applications.　Here,　an　artificial　tactile　perception　system　with　the　functions　of　perception,　memory,　and　feedback　is　realized　by　utilizing　a　triboelectric　nanogenerator　(TENG)　with　a　polymer　light-emitting　electrochemical　cell　(PLEC).　The　TENG　functions　as　a　tactile　receptor　to　convert　pressure　signals　into　electrical　signals,　and　the　PLEC　functions　as　a　light-emitting　electrochemical　artificial　synapse　(LEEAS)　with　the　dual　output　of　photoelectric　signal,　in　which　the　optical　signals　are　used　to　reflect　the　strength　of　the　pressure　and　the　electrical　signals　are　used　to　achieve　different　memory　levels.　Interestingly,　the　artificial　tactile　system　successfully　simulates　the　stress　response　and　pain　memory　of　organisms　to　different　levels　of　stress　signals,　which　is　quite　similar　to　the　actual　biological　perception　system　and　is　expected　to　build　artificial　skin.　©　1963-2012　IEEE.
